Directions for question:
The following Line Graph depicts the Mark-up percentage and the Discount percentage of six types of hand-woven Murshidabad-silk sarees A to F at a Tantuja Store in Kolkata, the West Bengal government handloom and silk saree shop.
Question:
What is the ratio of the cost price and the selling price of Murshidabad-silk saree type D ?
20:21
19:21
21:22
19:22
From the graph,
For Murshidabad-silk saree type D, marked price is 40% over cost price, and discount is 25% on marked price
We know that If profit percentage is p, mark up percentage is m and discount percentage is d, then
p = m – d – (m*d)/100
Hence profit percentage on saree type D = 40 – 25 + 40(–25)/100 = 5%.
So if the cost price is 100, the selling price should be 105.
Hence, the ratio of the cost price and the selling price of Murshidabad-silk saree type D
= 100 : 105
= 20 : 21.
